Just disconnect the blue side light connections to the indicators, just behind the fairing.
They have long thin terminals and you should be able to just get in without removing the fairing.

This does sound like the pulsar coils, I've come across this scenario loads of times. To check, remove the RH cover from the engine exposing the pulsar coils and ride it around with the cover removed. The air will cool the pulsars and it shouldn't cut out as quick as before. This should then confirm...

Failing that, "Zed man" also offers impeccable service on gauges.

This of any use?

Will looking at the turbo wheels in the prototype rebuild manual , this looks like the same A flow turbine? certainly not the smaller turbine, this wheel has the extension to the blade before it folds over which I dont think the smaller turbine has ? Ray, the one in yours is the F-flow. I got them ...

By the way, the speedo drive unit to use is from an early cb750 and its spacing is crucial to working correctly. There should be a 5mm spacer in there too which is not shown in the Rickman manual.

Ray. I take it you've pretty much retired now then due to the progress you're making? Great work and look forward to seeing the end result.

Here's a bit more about S+S in their non-turbo days too, in particular order

Ray. You are correct in that S&S pretty much did everything they could using the prototype as a mule. They tried with the standard 903cc, experimented with 960cc and settled with 1015cc. Their main problem though as I found out, was that all their findings were based on the prototype, which thro...

Next to the Unicorns horn I believe you'll find one
Best of luck.

As Garry says, should have a raised lip around the edge.
In the 70's you could buy a blank case set from Kawasaki UK.
S+S Performance did just that for their Silver Saxon production run, then stamped them up (badly) with their own unique number like my old bike here.

Terry. Tachos from 900 A4 Nd 1000 A1 are the same with 9k redline. 1000 A2 redline reduced to 8500.

I have many side light units if you need one, both standard and my LED conversion ones.

The z1 to Z1000A2 gauges are getting more and more expensive nowadays as you've probably found out! Which model speedo are you after...? There are noteable differencies and I suggest you see my listing to identify just what you want. https://www.ebay.co.uk/itm/183571284954 Failing finding a decent S...

No, but "Hi Steve", great to see you're still around
